Hi there, Honey might save you a few bucks, but it’s stealing from creators while doing so. Ouch. 🍯 In this week’s video, I tackle this issue head-on by designing a less evil version of Honey: meet Kale. 🥬 Kale is a browser extension that’s transparent, open-source, and creator-friendly. It doesn’t override affiliate cookies, gives users control, and still applies sweet discount coupons. But this video isn’t just about the what—it’s also about the how. I break down the full architecture, the...

Hi there, I just posted a new video, and it gets a bit personal. After four years of running ArjanCodes, I learned a tough lesson in 2024: trying to do too much leads to burnout, stress, and lower quality work. So I hit the brakes. Scaled back. Simplified. And guess what? The videos got better. I feel more focused. The team is happier. Now, heading into 2025, I’m embracing the Keep Things Stupidly Simple principle—both in software design and life. Watch this week’s video, if you want to hear...

Merry Christmas, everyone! 🎄 As the year wraps up, I just want to say a massive THANK YOU for all the support you’ve shown ArjanCodes in 2024. Together, we’ve hit an incredible milestone—260k subscribers! 🎉 This week, I’m hitting the pause button to spend some quality time with my family (and maybe eat a suspicious amount of cookies 🍪). That means no new video this week—but don’t worry, I’ve got big plans and exciting ideas for 2025. I can’t wait to dive into a new year of coding, learning,...

Hi there,Did you miss me dissecting, analyzing, and grilling your code? Well, the wait is over! ArjanCodes Code Roast is back! 🔥 In this week’s video, I’m diving into a project submitted by one of our community members: Tom Donahue’s Data Validator CLI. It’s a creative and ambitious project with some clever patterns—but also a prime example of how good intentions can lead to over-engineered code. Here’s what I tackled: ✅ Streamlining overly complex design patterns. ✅ Introducing unit tests to...

Hi there, If you’ve ever wished Python was more like Rust when it comes to handling errors, I have good news! Well, almost. 😉 In this week’s video, I introduce the returns package—a functional programming library that handles errors without exceptions. The Maybe and Result containers make error handling smooth, while railway-oriented programming keeps your code on track. But before you dive in, there’s a catch: this approach can add complexity, and it’s not ideal for every project. Watch the...
